Inside the build

Problem, constraints, decisions, and outcome.

What changed and why

01

Problem

A growing ERP frontend can quickly become a shared-file bottleneck where teams overwrite one another and business behavior leaks into generic UI code.

02

Constraint

Multiple feature teams need independent ownership while permissions, accounting values, and lifecycle rules remain controlled by backend contracts.

03

My contribution

Established the frontend foundation, module ownership rules, shared shell boundaries, typed API access, server-state conventions, and quality gates.

04

Technical decision

Organize work by business feature, use TanStack Query for server state, and keep the shared application shell separate from module behavior.

05

Outcome

Created a maintainable ERP frontend foundation that supports parallel feature delivery with automated build, lint, formatting, and test checks.
